How would the numbers - $-40,0$, and 40 appear on a horizontal number line?
A. 0 on the left end, -40 in the middle, and 40 on the right end
B. 40 on the left end, 0 in the middle, and -40 on the right end
C. 0 on the left end, and both 40 and -40 on the right end
D. -40 on the left end, 0 in the middle, and 40 on the right end
Answer
The correct answer is \(\boxed{\text{D. -40 on the left end, 0 in the middle, and 40 on the right end}}\).
Step 1 ：This question is about understanding the placement of positive and negative numbers on a number line. On a number line, numbers increase as you move to the right and decrease as you move to the left. Therefore, -40 should be on the left, 0 in the middle, and 40 on the right.
Step 2 ：The correct answer is \(\boxed{\text{D. -40 on the left end, 0 in the middle, and 40 on the right end}}\).
